Role of duplex doppler in evaluation of portal hypertension as a comparative study between bilharzial and non-bilharzial causes

Duplex Doppler has become powerful diagnostic tool in illustrating the morphology and haemodynamics of portal hypertension. We found that the maximum and mean blood flow velocity of the portal vein were less than control group with no significant difference between bilharzial and non bilharzial groups, while blood flow velocity in splenic vein was slower in 13 cases 3 cases. Blood flow volume did not show significant changes. Congestion index was elevated in portal hypertension with no significant difference between bilharzial and non billiarzial groups
